In 1930, after several failed attempts, a Stinson Detroiter seaplane flew to Bermuda from New York City, the first airplane ever to reach the islands. The flight was not without incident, as the aircraft had to land twice in the ocean, once because of darkness and again when it needed to refuel. Navigation and weather forecasting improved in 1933 when the Royal Air Force (then responsible for providing equipment and personnel for the Royal Navy’s Fleet Air Arm) established a station at the Royal Naval Dockyard to repair float planes (and supply replacements) for the fleet. In 1936, Luft Hansa began to experiment with seaplane flights from Berlin via the Azores with continuation flights to New York City.
In 1937, Imperial Airways and Pan American Airways began operating scheduled flying boat airline services from New York and Baltimore to Darrell’s Island, Bermuda. In World War II the Hamilton Princess Hotel became a censorship center. All mail, radio and telegraphic traffic bound for Europe, the US and the Far East was intercepted and analyzed by 1,200 censors, of British Imperial Censorship, part of British Security Coordination (BSC), before being routed to their destination. With BSC working closely with the FBI, the censors were responsible for the discovery and arrest of a number of Axis spies operating in the US, including the Joe K ring. In 1948, a regularly scheduled commercial airline service began to operate, using land-based airplanes landing at Kindley Field (now L.F. Wade International Airport), helping tourism to reach a peak in the 1960s and 1970s. By the end of the 1970s, however, international business had supplanted tourism as the dominant sector of Bermuda’s economy.
